Virtual environments
About the virtual environments
-
On this page you will find a list of virtual environments that I have made, using Unity3D and C#.
-
These environments usually have a primary function but might be used to other ends.
-
They are associated with the original scientific study for which they are built.
-
You can either run the build .exe in windows or get the source code (under conditions), and depending on your project I can help modifying the environment or building on a different platform (mobile, mac, linux).
-
If you want to get one of these environment or just learn more about them, contact me.
Virtual Rod and Frame Test
-
A very standard HMD supported rod and frame test in virtual reality, originally developed by Witkin et al. 1948 in order to assess field dependence. Procedure is fully described in this paper
-
16 trials, with a systematic counter balancing of the rod and frame rotation: -27°/+18°, -27/-18°, +27/-18°, +27°/+18° x2
-
Enter participant's code before beginning. Instructions are presented (audio + image) in French but can easily be modified or removed. Automatically export data (absolute °) in .csv with the date and time.
Starwalker
-
A HMD supported (3DRudder / no controller compatible) platform of mini games in VR: two space-invader like games, a wallbreaker game, a billard game, a bowling game, a hunting game

Threat
-
Threat is a CAVE, HMD and computer desktop supported virtual environment. It has 3 levels (scenes) which are automatically played in this order : 1;2;1;2;1;2;3.
This environment has been used for my master degree thesis. A video of the passation can be found on this page.
-
1 is a control condition. The participant starts in a dungeon's. He/she opens a door, and enters a large room. On the ground, beams indicate the way. The participant has two levers that he/she can trigger.
Then, the participant exit using a door at the back of the room.
-
2 is a heights condition. The participants starts exactly at the same place, but when he/she opens the door of the main room, the ground has collapsed, only the beams are still here. Below the room, the participant can see, 10 meters below, some water. The procedure is identical to 1.
-
3 is a threat condition. The whole scene looks exactly like 1, at the exception that when the participant triggers the second lever, a dark monster appears behind him/her.

Virtual Wisconsin Card Sorting Test
-
Virtual WSCT is a HMD and computer desktop supported virtual environment.
This environment has been used for my PhD Thesis, for a study called Neuropresence. A video of the passation can be found on this page.
-
This WSCT follows exactly the same procedure as the paper and pencil WCST, except that the participant is immerged in virtual reality, in an american Far-West cartoon environment.
-
The participant answers the test using tracked controller.
-
Each answer is automatically recorded (wrong or good), along with the duration of the test.
Spatial cognition evaluation
-
The spatial cognition evaluation is a HMD supported virtual environment. This environment has been used for my PhD thesis, for a study called Spatiopresebce, and for a study called Nav(i)r. A video of the passation can be found on this page. using 4 levels (scenes) played automatically in this order: 0;1;2;3;4
-
0 is a tutorial during which the participant can learn how to move in and interact with the virtual environment.
-
1 is a visit in the virtual environment, made of buildings from the Ancient Rome. Wood signs lead the way. The participant has to open some doors in order to reach the final point. But there are also "wrong" doors, which are closed. T
All the wrongs doors tried are automatically recorded, along with the participant's position (4 times / seconds) and the duration.
-
2 is a spatial cognition assessment. In the virtual environment, the participant is asked different question about what he saw or not during the visit. All the answers are automatically recorded.
-
3 is a new visit in the same virtual environment than 1, but the wood signs are gone. Participant is asked to redo the visit he has done in 1. All the wrongs doors tried are automatically recorded, along with the participant's position (4 times / seconds) and the duration.
-
4 is a a final question of spatial cognition evaluation, based on the second visit.
